MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a heterogeneous-substance accommodating device according tothe present invention is selectively described with reference to FIGS. 1to 8.

A heterogeneous-substance accommodating device 1 coupled to a mouth of acontainer includes an accommodating part 104 having a storage space 107within a main body 100. A soft foldable part F is disposed on an upperportion of the accommodating part 104, and an opening part 108 lengthilyextending downward is defined in the bottom of an upper portion of thefoldable part F.

Also, a main body mouth 109 is disposed on an upper portion of the mainbody 100, and a main body mouth sealing part 110 having a main bodymouth sealing hole 111 is disposed on an inner lower portion of the mainbody mouth 109.

Also, a sealing stopper 200 including a sealing hole sealing part 201for sealing the main body mouth sealing hole 111 is coupled to the mainbody mouth 109. An anti-forgery cover 300 is assembled to the main body100 including the sealing stopper 200.

In the accommodating device 1 as described above, a different kind ofsubstance is injected into a storage space 107 of the accommodating part104, and a lower portion of the accommodating part 104 is sealed byusing a sealing part S such as an aluminum sealing member.

Also, the foldable part F is configured so that the opening part 108breaks and punches the sealing part S when the foldable part F ispressed. In this process, the different kind of substance contained inthe storage space 107 drops into the container and then is mixed.

Also, the foldable part F is configured so that the foldable part F isexpanded outward and then folded when a force is applied from an upperside of the foldable part F. When the foldable part F is expanded, thefoldable part F may have a shape in which a foldable part upper portionfolding reference surface FA that is an upper outer portion is wide, anda foldable part lower portion folding reference surface FB that is alower outer portion is narrow.

Also, when the foldable part F is expanded, the foldable part F forms anexpanding reference surface FC having a large outer diameter between thefoldable part upper portion folding reference surface FA that is theupper outer portion and the foldable part lower portion foldingreference surface FB that is the lower outer portion.

Also, when the foldable part F is expanded, the foldable part F may bespread so that the an upward portion that is an upper side is expandedfrom the foldable part lower portion folding reference surface FB thatis the lower outer portion of the foldable part F.

Explaining the accommodating device 1 in more detail, FIG. 1 illustratesan exemplary example of the accommodating device 1. FIG. 1 illustrates astate in which the cover 300 including an anti-forgery rim 301 iscoupled to the main body 100. Here, a protrusion 302 is formed on aninner wall of a lower end of a side surface of the anti-forgery rim 301.

Also, the protrusion 302 is slightly spaced apart from the foldable partF. This is done for a reason in which, if the protrusion 302 contacts anouter circumferential portion of the foldable part F from the beginning,resistance occurs when being sealed again because an outer configurationof the foldable part F is expanded while the foldable part F is folded.

FIG. 2 is a view of a state before the cover 300 is coupled to the mainbody 100.

FIG. 3 illustrates a state in which the foldable part is folded whilebeing expanded outward when the sealing stopper 200 is pressed.

FIG. 4 illustrates an example in which the main body 100 is primarilyinjection-molded, i.e., illustrates a state before the foldable part Fof FIG. 5 is formed.

For reference, FIG. 4 illustrates a state in which a resin moves in adirection of the accommodating part 104 through the protrusion part 112at an upper side of the opening part 10. This state is an example of amethod for manufacturing a mold.

Also, even though a protrusion part end 113 is separated in a momentwhile being injection-molded, the protrusion part end 113 immediatelyreturns to its original position.

Also, as illustrated in FIG. 4, a foldable part adhesion surface 114 isformed on an outer circumferential portion of a lower end of the mainbody mouth 109. In this state, FIG. 5 illustrates a state in which thefoldable part F is molded by a multi injection molding machine.

As illustrated in FIG. 5, it is seen that the upper portion of thefoldable part F closely adheres to the foldable part adhesion surface114.

Also, although an auxiliary protrusion pat 115 is disposed on theopening part 108, and a container neck first sealing part 105 and acontainer neck second sealing part 106 are formed on an outercircumferential portion of the accommodating part 104, the presentinvention is not limited thereto. For example, other modified structuresmay be allowable.

Also, a first screw thread 102 and a second screw thread 103 which havestandards different from each other are disposed on an inner portion ofa side surface 101 that is an outer circumferential portion of the mainbody 100. Each of the first screw thread 102 and the second screw thread103 may be used to be selectively coupled to each of different containerneck screw threads formed on a container neck.

Also, a dotted line shown in FIG. 5 represents a state in whichcontainer necks 100 having shapes different from each other contact thecontainer neck first sealing part 105.

In case of FIG. 6, the expanding reference surface FC in which a centralportion of the foldable part F is expanded is illustrated. In thisstate, the expanding reference surface FC is formed while the foldablepart F is swelled in a folded shape due to resistance when the main body100 is separated (dispensed) from the mold.

In case of FIG. 7, when the sealing stopper 200 is pressed, the foldablepart F is folded while being spread outward. In this process, thefoldable part adhesion surface 114 receives resistance in a direction ofan inner wall of an upper end of the accommodating part 104, and thus,the foldable part F is not folded any more to stop. In the situation ofFIG. 7, when the applied force is released, the foldable part Fimmediately returns to an upper side (see FIG. 8).

Also, in the situation of FIG. 7, when the sealing stopper 200 islifted, the sealing hole sealing part 201 gets out of the main bodymouth sealing part 110 to form a main body mouth sealing hole 111.

In case of FIG. 9, the folding prevention protrusion FD is formed on thebottom of an upper end of the foldable part F so that the foldable partis not folded any more to a predetermined degree or more. Here, thefolding prevention protrusion FD may be selected so that the foldingprevention protrusion FD does not cover a top or bottom surface of thefoldable part F.

In FIGS. 11 and 12, the main body mouth 109 for accommodating thesealing stopper 200 is formed on the main body 100. The main body mouthsealing part 110 is disposed on an inner lower end of the main bodymouth 109, and an elastic sealing part 119 is disposed inward from themain body mouth sealing part. In use, as illustrated in FIG. 11, theelastic sealing part 119 is closely attached to the sealing hole sealingpart 201 and thus is sealed.

Referring to FIG. 13, a first screw thread 102 is disposed on a lowerportion of an inner wall of a side surface 101 of the main body 100 ofthe accommodating device, and a second screw thread 103 having astandard different from that of the first screw thread 102 is disposedon an upper portion of the inner wall. The side surface 101 on which thefirst screw thread 102 is formed may be a side surface 101 having ashape that is spread outward. An auxiliary screw thread 121 having aninner diameter greater than that of the first screw thread 102 is formedon the inner wall of the side surface 101 having the spread shape, i.e.,an isosceles trapezoid shape.

Also, the auxiliary screw thread 121 includes a three-line auxiliaryscrew thread 121 so that the auxiliary screw thread 121 is coupled to acontainer neck having a container neck screw thread with a 30 MMstandard. The auxiliary screw thread 121 may have three lines that areangled at about 120 degrees, and each of the three lines of theauxiliary screw thread 121 may have a length of about 10 MM to about 30MM, but is not limited thereto.

In case of FIG. 14, an example in which the main body 100 is coupled toa container neck 1000A having a large size is illustrated. Particularly,a state in which the auxiliary screw thread 121 is hung on and fixed tothe container neck screw thread 1001.

In case of FIG. 15, a modified example of an opening part 108A formedinside an accommodating part 104A is illustrated. Here, an opening end122 is split by a space 123. In use, the opening end 122 punches twopositions of a sealing part SA. This is shown as a dotted line in FIG.15.

In case of FIG. 16, a tapered punching pin 124 is disposed on a side ofthe opening part 108A. In use, the opening end 122 punches the sealingpart SA that seals a lower portion of the accommodating part 104A toform a dropping space SC, and the punching pin 124 forms a punching partSB.
